In a portion of code of my app (collision detection part) i need to
remove an object from an array of objects,
when two distinct objects crashed i decrement a life counter, and
if this is equal to zero the object must be destroyed, but when the
counter
reach de zero and the object is destroyed my app crash. Some one can
help me with this problem, here is the code, and thanks in advance:
You're removing an object from an array while iterating through it.
Think carefully about what this is doing to the indexes of objects in
the array, and you'll probably see what's going on.
You probably ought to move to some sort of "mark-and-sweep" algorithm
here, rather than mutating the array while iterating through it.
